Re: WTB Older 3 Channel or 4 channel

Rather have that 3300, I don't get much of a difference between the 403 and the 3150

understandable.

403a has twice the power of the 3150 and the 3300c has more power to the substage.

403a is 50x2 @4 + 200x1 @2

your 3150 is 25x2 @4 + 100x1 @2

the 3300c is 60x2 @4 + 360x1 @2

also, the 3300c is much larger than the 403a, and can be difficult to locate. it also has a 90 deg bend in the heat sink channel which reduces cooling efficiency, and it has thermal flaws in the power supply. both of my 3300c are on my bench in need of improved thermal management for power supply components. the stock design was/is flawed. the 403a addressed those issues and doesn't have the drawbacks.

a 603x would be a better option for you if you want more power 75x2 @4 + 300x1 @2

Was going in my GTO, so enough room for any size amp in the world, lol. I just picked up an Orion 150R that I hear is pretty rare. does what I want too, [email protected] and [email protected]
